Tuning kit Weihrauch HW77/97 Export cal. 4.5 - AirJoe Premium

This extensive PREMIUM tuning kit was developed together with the well-known English author and tuner Lyndon Lewington of ARC Tuning. The successful V-Mach tuning kit by Steve Pope served as a reference. The fully equipped kit is designed to increase precision without increasing the power. All components are carefully adapted to each other individually. First-class ARC piston springs are used, identical in construction to the V-Mach springs. A ARC Tuning piston seal, a piston inner sleeve, spacers, hinge pin and high-quality grease are included in the kit.

According to German law, the installation may only be carried out by a gunsmith.
